- 2.5V to 15V Input and Output Voltage Range
- 1.5A Continuous Output Current: VIN ≥ 5V, VOUT = 5V, PWM Mode
- Single Inductor
- Accurate RUN Threshold
- Up to 95% Efficiency
- 800kHz Switching Frequency, Synchronizable Between 600kHz and 1.5MHz
- 49µA No-Load Quiescent Current in Burst Mode® Operation
- Output Disconnect in Shutdown
- Shutdown Current < 1µA
